30、 of components used in residential ventilation systems to establish the main characteristics as identified in EN 13142. Part 1 and Part 2 relate respectively to the externally/internally mounted air transfer devices and the exhaust/supply air terminal devices, which are used in the residential venti
31、lation. Part 3 considers performance testing of range hoods for residential use, and is based on an IEC standard. Part 4 consists in some special measurement conditions for fans to be used in the residential systems, when applying the general ISO methods (as ISO 5801). Part 5 gives test methods for
32、cowls and other roof outlets. Part 6 gives test methods for exhaust ventilation system packages used in a single dwelling. Part 7 gives test methods for supply and exhaust ventilation unit used in a single dwelling. Part 8 gives test methods for un-ducted supply and exhaust ventilation unit used in
33、a single room. The standard incorporates many references to other European and International Standards, especially on characteristics other than the aerodynamic characteristics, for instance on acoustic characteristics. In most cases some additional tests or some additional conditions are given for
34、the specific use in residential ventilation systems. The standard can be used for the following applications: ? laboratory testing; ? attestation purposes.

35、ropean Standard specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal and acoustic performance, and the electrical power of a un-ducted mechanical supply and exhaust ventilation unit used in a single room. In general, such a unit contains: ? supply and e
36、xhaust air fans; ? air filters; ? air to air heat exchanger for exhaust air heat recovery; ? control system. Such equipment can be provided in more than one assembly, the separate assemblies of which are designed to be used together. This European Standard does not deal with ducted units or units wi
